strsep - extract token from string
Návod, kniha: Linux Programmer's Manual
#include <string.h>
char *strsep(char **stringp, const char *delim);
If *
stringp is NULL, the
strsep() function returns NULL and does
nothing else. Otherwise, this function finds the first token in the string *
stringp, where tokens are delimited by symbols in the string
delim. This token is terminated with a `\0' character (by overwriting
the delimiter) and *
stringp is updated to point past the token. In
case no delimiter was found, the token is taken to be the entire string *
stringp, and *
stringp is made NULL.
The
strsep() function returns a pointer to the token, that is, it returns
the original value of *
stringp.
The
strsep() function was introduced as a replacement for
strtok(), since the latter cannot handle empty fields. However,
strtok() conforms to ANSI-C and hence is more portable.
This function suffers from the same problems as
strtok(). In particular,
it modifies the original string. Avoid it.
